GDM Fast-Tracks Cashflow at Challenger Gold Mine

Great Divide Mining Ltd has moved to accelerate near-term cash generation at its wholly owned Challenger Gold Mine in Adelong, NSW, utilising historical mullock stockpiles on site for initial process plant feed. The mullock provides a low-cost and immediate production feed as commissioning works continue. The priority mullock sites — Currajong, Great Victoria/Annetts/Research, Donkey Hill and Radcliffe/O’Briens — comprise stockpiles ranging from 10,500 to 35,000 tonnes at average gold grades between 1.38g/t and 1.6g/t. “The mullock sits at surface, eliminating drilling and conventional mining costs, with short off-road haulage distances to the upgraded Challenger processing plant,” said CEO Justin Haines. “Seizing this opportunity materially strengthens the Company’s restart strategy,” he said. “This is exactly the kind of opportunity we look for at historic goldfields. The material is already mined, it’s sitting at surface, and at grades higher than some operating hard-rock mines,” Mr. Haines continued. “With record gold prices and minimal recovery costs, mullock processing provides a straightforward pathway to early cashflow while we continue ramp-up activities across the broader Challenger site,” he said Local contractor L.A. Broome Contracting will mobilise within two to three weeks to commence haulage of mullock to the ROM pad, ensuring consistent plant feed as commissioning progresses. GDM is taking a “treat-all” strategy to the mullock to maximise gold recovery. Challenger, part of GDM’s 70km² Adelong Project, is being recommissioned under a staged “crawl-walk-run” restart plan designed to establish commercial production while expanding operational capacity. “Cleaning up the mullock onsite is a win for the environment as well,” said Haines.

Why India joining the US alliance on AI tech is an opportunity for Australia

Arup George, Research Manager, UNSW Sydney India has formally joined the United States’ flagship international alliance on artificial intelligence (AI) supply chain security: “Pax Silica”. Officials from both countries signed the Pax Silica declaration on the sidelines of a major AI summit in New Delhi last week. This initiative seeks to bring together US “allies and trusted partners” to lead the global AI race. Australia was a founding member. While Taiwan looks set to keep dominating advanced AI chip manufacturing, it relies on a complex international supply chain, with critical aspects dominated by China. When essential elements come from a narrow set of suppliers, even minor disruptions can ripple globally. Diversity matters. That’s why Australia and India now have an opportunity to become essential international players. Why Washington is building an alliance AI is rapidly becoming a foundational resource of the 21st century across manufacturing, logistics, finance, healthcare, drug discovery and defence. The Pax Silica alliance recognises different countries play distinct and critical roles in building the tech that powers AI. For example, advanced chip-design expertise is concentrated in the US. Key semiconductor manufacturing equipment comes from the Netherlands and Japan. South Korea produces a small but important slice of the world’s AI computer chips. But the biggest chip maker by far is the tiny island nation of Taiwan. Healthcare AI robots at an exhibition at the India AI Impact Summit. AP The world’s chip factory Taiwan produces 90% of the world’s most advanced AI chips, designed by US firms such as Nvidia, Google and AMD. These firms overwhelmingly depend on Taiwan Semiconductor Manufacturing Company (TSMC). This remains the only manufacturer that can produce the world’s most cutting-edge chips at scale. And their advantage extends beyond making chips. TSMC also possesses unique advanced packaging capabilities that integrate AI accelerators with high-bandwidth memory chips. This is essential for achieving the tight coupling of “compute” […]

300 per cent boost to clean, green energy uptake will see surge in lifting and shifting of specialist machinery

As Australia presses the button on accelerated conversion to clean, green energy, more industrial plants, resources sites and commercial buildings will face lift, shift and placement issues for the specialist machinery involved. As the move to clean, green electrical energy accelerates to meet Australia’s 2030 emissions deadlines, huge quantities of heavy new electrical plant will need to be safely and delicately lifted, shifted and positioned within confined places. New turbines, generators, transformers, switchboards, charging infrastructure, batteries, and emergency backup plant – some of which weighing 50-100 tons or more – will be needed at transport and logistics facilities, industrial and social infrastructure construction projects, factories, food and beverage process plants, warehouses, and mining, gas and energy projects. “Australia faces a huge increase in new electrical plant capacity over the next decade, with the Australian Energy Market Operator (AEMO) forecasting a near tripling of total generation and storage capacity by 2035 to reach 190 gigawatts (GW), up from 82 GW currently,” says Australian actuation, isolation and suspension specialist Air Springs Supply. “This massive expansion of new energy inputs is driven by the retirement of coal-fired power stations (90% expected to close by 2035), increasing electricity demand from electrification of transport and industry, and the national target of 82% renewable energy by 2030,” says Air Springs Supply Technical Product Manager Vinh Lam. The boost in electrical energy generation will in turn lead to a surge in demand for new plant and infrastructure across industrial and commercial developments, both in space-efficient new development and repurposing of limited space within existing facilities. Preparing for heavy lifts involved inside factories, workshops, and materials processing plants can pose accessibility and safety challenge in confined spaces, especially where overhead cranes are impractical.

A decade of natural gas delivers $127 billion boost to QLD economy

Queensland’s natural gas industry contributed $127 billion to the state economy while supporting nearly 60,000 jobs in its first decade of LNG exports, economic analysis commissioned by Australian Energy Producers has found. The Economic Impact of Queensland Natural Gas and LNG 2014–24 report, by Lawrence Consulting, found the industry directly spent $58.6 billion in Queensland over the last decade, including $42.5 billion with more than 3,000 local businesses, community groups and charities. Australian Energy Producers Queensland Director Keld Knudsen said the findings reaffirmed the gas industry is a key driver of Queensland’s economic prosperity and energy security. “As Queensland’s natural gas industry celebrates the significant milestone of a decade of LNG exports, it is worth reflecting how the industry has transformed Queensland’s economic and energy future,” Mr Knudsen said. “This investment is paying dividends for all Queenslanders, delivering reliable and affordable energy for millions of homes and businesses, while unlocking billions of dollars each year in economic activity and government revenue to help fund the essential services and infrastructure our communities rely on.”. Key findings of the sector’s contribution in the period 2014-24 include: $127 billion added to Queensland’s Gross State Product $58.6 billion spent across Queensland over the decade which comprised: $42.5 billion in spending with 3,178 businesses and 307 community groups $7.2 billion in payments to the Queensland Government $695 million paid to local councils $8.2 billion in wages to Queensland workers Mr Knudsen said Queensland’s LNG export industry is an integral part of regional communities across the state, underpinning local jobs, businesses and services. “Every LNG tanker that departs Gladstone represents around $4.5 million in royalties paid to the state, $11.2 million in spending with local businesses, and millions more in salaries, community contributions and taxes.” “Long-term policy certainty is key to driving more investment in new gas supply and […]

China’s greening steel industry signals an economic reality check for Australia

Cristoph Nedopil, Director Griffith Asia Institute, Griffith University Australia has flourished as an export powerhouse for decades. Much of this prosperity has been driven by the nation’s natural endowment with two important raw products for producing steel the traditional way: iron ore and metallurgical coal. Worth more than A$100 billion in 2024, Australia’s iron ore shipments to China make up about 55% of everything we export there. But a transformation has been taking place in China’s steel industry, which is under intense pressure to decarbonise. Earlier this year, Beijing formally expanded its national emissions trading scheme to cover steel production. And just this month, it issued another decree requiring steelmakers to increase their share of green energy in steel production. Prime Minister Anthony Albanese’s recent visit to China may have looked like a celebration of normalised diplomatic or trade ties. Behind the scenes was a quiet but critical economic pivot. Australia’s economic future depends on whether it can green its exports fast enough to meet the decarbonisation needs of its biggest market. A greener China In China, no new permits for coal-based steelmaking appear to have been issued since early 2024. However, China has been approving new, greener steelmaking capacity, using electric arc furnace (EAF) technology, the main low-emissions technology in steel. These furnaces use high-voltage electric arcs, powered ideally by green energy, to melt scrap steel or what’s known as direct reduced iron (DRI). Through that process, they limit carbon emissions by reducing the use of thermal coal for electricity and metallurgical coal for iron making in blast furnaces. In total, China has now installed enough electric arc furnaces to produce more than 160 million tonnes of steel annually. That’s about the same as the total steel output of Japan and the United States combined. China’s current 10% share of steel production from electric arc furnaces still remains below the country’s 15% target. But […]

Got Solar? Share the power: National energy trial needs volunteers

Australians with rooftop solar are being invited to take part in a first-of-its-kind research project exploring how communities can buy and sell clean energy directly with each other. Led by Deakin Business School, the Virtual Energy Network (VEN) study is testing how households and small businesses can benefit from peer-to-peer energy trading – allowing those with solar or battery systems to sell their excess energy to others who don’t have solar but want to access greener, cheaper power. ‘This is a potential game changer for how we share renewable energy,’ said Dr Andrea La Nauze, the project’s lead researcher and an energy economist at Deakin University. ‘It’s about empowering people with solar to decide where their surplus power goes and how much they charge for it, while giving more Australians access to clean energy – even if they can’t install panels themselves.’ The trial is now recruiting 400 participants from across Australia, including individuals and community groups, to join an online platform where sellers and buyers of energy can connect based on pricing preferences. Participants don’t need to live in the same suburb – or even the same state – but they do need to be with the same energy retailer. Sellers could include households, small businesses, or even larger operations with multiple properties. For example, parents could share their excess energy with their children or other extended family members to help with cost-of-living pressures. Buyers, meanwhile, can benefit by accessing power that’s cheaper than typical electricity prices, while supporting local renewable energy use. The VEN trial is funded through Energy Consumers Australia’s Grants Program and delivered in partnership with QuantumNRG, ReThink Sustainability and WinZero. Dr La Nauze said the project was inspired by a successful community-led energy trading initiative in Wingecarribee, NSW, and could help lay the foundation for […]

AREMA calls for urgent reform on incentives for hot water heat pumps

New South Wales and Victoria, supported by initiatives taken by the Commonwealth Government, created bold programs to support electrification and net zero through providing rebates to home and business owners that install hot water heat pumps. While well intentioned, there are major flaws within these programs, including: Safety – some of the equipment on the market have inherent risks and are being installed by an untrained cohort. Performance – some of the hot water heat pumps for sale simply do not give the electricity savings and hot water indicated. Fraud & waste – unscrupulous and untrained people are selling and installing poorly made and designed products to an unsuspecting population to obtain the incentives. Industry has been engaging on these issues with governments, for the last couple of years, but there remains no certainty that significant reforms are forthcoming. AREMA argues that if reform is not possible over this year, then the incentive programs in place now should be put on hiatus until these issues are resolved. So what needs to happen? Product standards for safety and minimum energy performance needed to be in place. We are still waiting for these to be developed, implemented and put into regulations. The trade needed to be trained and licensed. The knowledge and skills needed includes both plumbing and refrigeration expertise. The licensed plumber and fridgies out there needed to have their skills lifted before these programs recommence. There needed to be a robust compliance regime to ensure questionable products and people are kept out the market. To be clear, there are well-engineered hot water heat pumps on the market from all over the world, that are being installed by competent and experienced technicians. These products deliver hot water efficiently and with a markedly reduced electricity bill and lower emissions Sadly, these products […]
